GUARD FOR VARIETY MOLDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 252,313, dated January 17, 1882.

Application filed October 10, 1881. 7 (No model.) a

To all whom it may concern:

Be it known that I, GOTTFRIED GRILL, .of Baltimore city, State of Maryland, have inventedcertain new and useful Improvements in Guards for VarietyMolding-Machines; and

I hereby declare the same to be fully, clearly,

; molder, and when they do occur they are severe and serious, resulting in the loss to the workman ofone or more fingers, if not of the use of the hand entirely.

I have endeavored to obviate the danger of accidentby providing a guard consisting of a bell-shaped device adjustably mounted at the workside of the knives, andadapted as well to stop a flying cutter as to prevent access of the hands to the knives while in motion.

In the drawings, A is the table; a, the shaft, having cutters b and pulley a, all of the ordinary construction.

In a circle about the shaft plates j j are countersunk flush with the table, leaving a dovetail annular groove between the plates, in which fits a block, J, having a rod, I, which projects up through abracket, G, and carries a clamp-lever, t", on its threaded end. The arm 0 of the bracket is provided at c with brasses which are setup, by means of screws D, against the-top of the shaft a, steadying both bracket and-shaft.

A bell-shapedcasting, (I, rests around the the cutters, high enough above the table to let the work pass under,.and low enough to stop a knife or cutter should one fly out from the shaft. Adjustability of this bell with reference to the shaft and table and its firm sup: port are attained by means of an arm, E, threaded atf intoa socket on one side of the bell,

and serrated or roughened at e, asshown. It is clamped at any desired height above the table and any desired distance from the shaft by means of the bar 13, the ends of which pass through the end of the arm 0 and carry setscrews 0 e.

For greater security and steadiness (though not absolutely essential) I provide two slotted arms, H it, having a bar, g, projecting downward through a lug, G, on the bell, whereit is secured by a screw, 70, the lower end, I, serving as a guide in bringing the wood to the cutters. The arms H h are clamped to the bracketarm 0 by screws h h, as shown.

The entire device may be readily moved around the table upon loosening the clamp t,

and the various adjusting devices admit of the bell being brought to any desired position.

The guard is readily applied to the ordinary molder, it being only necessary to chuck the table in a lathe and turn the groove for the plates j.

Having thus described my invention,'what I claim as new, and desire .to secure by Letters- Patent, is g 1. In combination with the table having annular undercut groove, the bracket pivoted upon the cutter-shaft and provided with a clamp for securing it atany pointin the groove, and with an adjustable bell wholly or partially inclosing the knives, as set forth.

2. In combination-with the table having annular undercut groove, and the bracket having adjustable'bushing for thecenter shaft, and

the clamp t' J, the bell-shaped guard d, as set forth. I 3. In combination with the guard dand bar F, secured to the guard and vertically adjustable upon-the bar 0, the bracket 0, mounted upon the shaft, and the guide I, as set forth.

4. In combination with the bracket (1 0, adjustable about the shaft and pivoted thereon, the guard d, arms H, h, G, and E, having clamping-screws for securing and admitting of the adjustment of the parts, as set forth.
